dc.description.abstractThree samples have been analyzed, two of them belong to the volcanic ones from the IPB and a third to the rocks plutonics of the BSN. The age belonging to the granitoid of Campofrio is of 354,4 +5/-4 m.y. The ages obtained for the volcanic materials are of 347,5 ± 7,5 m.y. for the sample of Zufre and of 353 ± 2 m.y. for the rhyolltes of the SE of Nerva. Being based on the scales of the geological time, this interval of ages correspond to the Tournaisian, and moreover, suggests that the intrusion of the Sierra Norte and Be/a batholiths happen at the same time. These ages also coincide with the ages obtained for the main event of the volcanism that the IPB generates. Therefore, you can conclude that both types of rocks (volcanics and plutonics) they were formed at the same timeen_US
